The simultaneous determination of 45 organophosphorous pesticides (OP, 8 phosphates, 14 phosphorothioates, 15 phosphorodithioates and 8 miscellaneous OP), which were registered or had been registered in Japan, was performed by gas-liquid chromatography (GLC) with a flame ionization detector. Three kinds of liquid phases (2% OV-1,1.5% OV-17 and 3% QF-1) under isothermal and temperature-programmed operations were employed for the detection of OP. The retention indices of 43 OP except ESP and trichlorfon were determined by GLC systems on OV-1 and QF-1,but 41 OP except ESP, trichlorfon, acephate and menazon on OV-17. The effectiveness for a series of GLC systems was evaluated by using the concept of discriminating power (DP). The highest DP for single GLC system was given by isothermal analysis on QF-1 (DP=0.931,numbers of OP=43 and error factor=50). The most effective DP for two GLC systems was given in combination with OV-1 and QF-1 with the temperature-programmed analyses (DP=0.980,numbers of OP=43 and error factor=50).
